Affordable price point
Many reviewers explicitly cite the low cost as a key reason for purchase, often comparing it favorably to pricier tea tree masks while still delivering good essence volume.
Reputation for calming/sensitive skin ingredients
Tea tree extract reputation drives purchases from buyers seeking gentle soothing for irritation, redness, rosacea, and acne without harsh reactions.
Repeat purchase/brand loyalty
A large number of reviews mention this being a second, third, or repeat order, and buyers say they trust and stock up on SOME BY MI masks generally.
Bundled freebies/promotions
Several Japanese-language reviews mention purchasing partly for included samples or gifts (e.g., mini eye cream) bundled with the mask.
Recommendation for acne-prone or problem skin
Reviewers frequently bought it specifically to treat active breakouts, congestion, or post-procedure (e.g., microneedling) skin recovery.
